CHARLES M. LUNGHEN, F BAYONNE, NEW JERSEY, ASSIGNR TO THE .RAILWAY UTILITIES COMPANY, A CORPORATION 0F NEW JERSEY.

` To all'whom 'it concern:

" such relation.

" to'maintainfmantles lin a state residing at Bayonne, inthe county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Vapor Mantle-Burners, of which the following is a full, clear, land exact description,-

such as will enable others skilled-inthe art to which it appe'rtafins to make and use-thelov '.1 v

same.

This invention relates broadly to 'illuminating apparatusfbut inasmuch as certain advantages characterlstlc 'of the inventionI promlnently appear when it is resorted to as a vapor burner ofthe inverted type, it'will be conducivev to clearness -to disclose it` through one or more of itsembodiments in lhis invent-ion has in view, among other obgects, the provision of aburner adapted cence andwhich is particularlyfadapted for lthe useof liquid fuels.'

More particularly, this invention aims at a-burner construct1on 1n which the superheatin coils for the liquid fuel'will be arran e directly in the 1 path of the: rising pro ucts of combustionf so asto be' maindescription.

hensible to others vskilled'in its relating art,4`

This 'invention in general-seeks to `pro ada ted" yfor the employment of mantles w 'ch, rom;

an operative standpoint, will in *practical*r usage ,fpos'sess' a high, degree 4of efficiency"v and durability and which, structurally-comi` sidered, 'will be vof the greatest 'possible-sim-z ormed shank lfadap'ted to detachably recei veA an inverted mantle.; f

Other' objects and advantages-will be in and in part pointed out in .the'following The invention accordingly consists inthe .features o f construction, combinations of elements and arrangement of parts which",l will be exemplified in the construction here-- inafter set forth, and the sob' e ofthe ap` lication of which willbe claims.A

1 parts'are similarly referred to by like char- Beit known that LCHARLES M. LUVGREN,v

acters of reference throughout all the iigures of which:v Figure 1 Yis a vertical section of la vapor burner embodying this invention 'wherein the various parts are shown in theirhormal relationshi f Fig 2 is r`a vertical section of the device shown in Fig. 1 taken transversely to-the section of Fig.,1. Fig. 3 is 'A a top plan view of thebody portion ofthe zburner;l Fig; lilis a view of .a device fundamental-ly'simila-r tolthat shown by Fig. 2,

- Contlnulng now with :timore-detailed de'- -scription-of the herein disclosed'. embodiments of this invention, with such occasional referenceto thedrawings as may v'facilitate yan understanding of thel same, 1 denotes the' Vbody portion of the burner, which bodyrportion may provide flanges Qadapted for su porting theV sameI as may be desiredfn the center of the body portion. there4 is a mixing andexpansion chamber 3 into which the' air inlets 4 and the gas inlet 5:0 en.

YThejsupply of air may be. easily contro led by means1 of-the val'veatthe outer end of each'air'inlet'. 1This'valve comprises a cap l6 having'one `or more apertures 7 and in screw threaded en agement with. the member 8 so as to ena le the area. of the apertures 7 to be reduced or enlarged in capacity.

' 'Depending fromthe body portion l and 1n` communicationwith the central` Amixing lcham-ber thereof isa burner tube 9 whic referably has a threaded or otherwise whose convolutions l'will lie directly in the path of the hotproducts ftorn'To thisend, I have arran ed a. .conduit g 1-1 around the upper part of t e burner in :the form of -a coi fective vaporizingV area of this-upper coil,

there is arranged within the latter areticulated metallicnetwork 12 which may be formed of ordinary .brass screening. l vIn this PPBI portion as shown by burner tube as illustrated by 16=an lower coil.

of the'lower coil 15 receives the preliminarily heated fuel from suchend. This arrangement very well Aserves to tightly connect the larger upper coil to the smaller The lower coil 15 convolutes around the upper end of the de ending iinally enters the body portion at 17 lso as to com y in manufacture and cleaning, the outer end -of the passage 18'may be closed byV means of municate with the transverse passage 18, whichinl turn communicates with the chamber 19 of the needle valve. For convenience a screw 20. j

Ihave vdeviserilra very eHective valve for use in connectionwith my -vapor burner and in which I make use of an ordinary needle.

lThus, '-Ii-f'have provided a need le`holder 21 which is in screw threaded relationith the bodyportion so as to be readily adjustable thereon. The needle holder provides a small "bore 22 Avof suiiicient size to permit thepointed end'of a needleto emerge therefrom but incapable of allowing the thicker hank of' the needle to pass ltherethrough. he shank of the needle 23 extends into the bore 24,

which in turn carriesthe' Screw 25 whichabuts .the end of the needle and ylteeps it securely in place.

In the modiiication shown/.by Fig., i I

have employed 4a, multiple injector 4so as to better adapt the burner for fuels which are l. of a conparatively rich nature, such as gasoi lene an the like. `This modification consists in arranging over the nipple 5 a tube 26 having one or more air inlets 27 and terminating at 28. This tube is so arranged and proportioned as to provide a channel 29 therein, such fuel will have become partially,I ,if not entirely, vaporiz'ed prior to beingfor conveying-air toward the discharge end of the tube 26 so that the partially completed mixture which emerges from the end of the tube 26 may be admixed with additional `air prior to being projected downwardly through the depending burner tube.

various objects and ends had in View.

In operation, the li uid fuel first passes aroundl the lupper coi of the heater and owing to the fact that it has infiltrated through the reticulatedl metallic structurel received by the lower coil. In passingy through the lower coil, the vapor will be brought to a still higher temperature andl ector. i
